<p>713,976. Carburetting water gas. HUMPHREYS & GLASGOW, Ltd. Dec. 31, 1952 [Feb. 1, 1952; Aug. 13, 1952], Nos. 2762/52 and 20369/52. Classes 55 (I) and 55 (2) In a cyclic process for carburetting water gas with heavy oil, carbon residues are deposited during the gas-making period in a bank of checkerbrick and are subsequently burned off with air which has been highly heated by passing through another checkbrick bank, both banks being heated by blow gas during the blow period. The apparatus consists of a generator a, a carburetter b and a superheater c. In Fig. 1, the carburetter contains two checkbrick banks 1 and 2 separated by a space 5 into which heavy oil can be sprayed through a nozzle 6. The cycle consists of a gas making period during which the injected oil is cracked in space 5, the carbon formed being retained in bank 2. The run is followed by a blow during which both banks are heated by a blow gas and then a carbon-burning period during which air is admitted to the top of the carburetter through a connection 3X, is highly heated in bank 1 and burns off the carbon in bank 2. To dispense with the separate carbonburning period, the carburetter may have three checkerbrick banks 1, 2 and 7, Fig. 2, the pipe 3 from the generator entering the space between banks 2 and 7 whilst oil can be sprayed into the space between banks 1 and 2 from nozzle 6. In this case the blow is carried out in two stages. In the first stage, blow gases pass up through banks 2 and 1 and discharge through a stack 9. In the second stage, the gases pass downwardly through bank 7 to the superheater whilst air is admitted at 10, is heated in bank 1 and burns carbon deposited in bank 2 during the previous gas-making period. During the run, oil is sprayed into space 5 and a small quantity of steam is admitted at 11, carrying the oil gas downwards to mix with the flue gas entering the carburetter from pipe 3.</p> |
